The Components of Mobility Scooters
Generally, the mobility scooter is composed of four parts: battery, electric wheel hub, controller, charger and body part. For manufacturers with higher safety requirements, the overall design is based on the design of the car. The vehicle is generally divided into several parts: the power supply system, the front axle, the rear axle, the controller, and the frame.
Because the current cost of lithium batteries is relatively high, general manufacturers use lead-acid batteries. Generally, a group of batteries is composed of multiple 12V batteries connected in series to form a battery pack, which is used as an electric power supply system. According to relevant national regulations, the voltage of mobility scooters must not exceed 48V;
Motor hubs are divided into: brushed toothed high-speed electric wheels (referred to as high-speed motors or sound motors), brushed toothless low-speed electric wheels (referred to as low-speed motors or silent motors) and brushless toothless program motors (referred to as program motors);
The controller is classified into four types: full action type, intelligent type, dual control type and non-zero start type according to the control mode. The control system consists of the main controller, instrument display, speed regulating handlebar and brake power off handlebar. The function has the functions of stepless speed regulation, brake power-off protection, undervoltage protection and overcurrent protection; the charger is classified into lotus plug type, ordinary computer plug type and special computer plug type according to the output plug. According to the charging performance, it is classified into ordinary online maintenance chargers and fast charging online maintenance chargers. According to the charging voltage, it is classified into 24V, 36V and 48V.
